本文的主要目的是探讨一些问题的概念周围的DCD作为一个“特定”的学习困难。与DCD的评估和识别有关的问题得到解决。我们提出的论点是来自一项研究中获得的数据，该研究比较了224名因学习和注意力问题（但不是运动困难）而被提及的儿童和155名典型发育中的儿童。这379名儿童都进行了一系列正式和非正式的测试，包括几个感觉运动测试。工作标准的儿童分类为DCD的推导。除了在这组儿童中获得的DCD的高患病率数据外，在DCD和其他发育障碍（如踏步残疾和注意力缺陷/多动障碍）之间观察到的共病程度也很惊人。这些结果促使我们重新评估离散的诊断类别的有用性，并考虑一般儿童疾病的重新概念化。有人提出，在儿童疾病中发现的合并症反映了一个单一的潜在病因：非典型脑发育。这种缺陷可能以各种方式表现出来，包括DCD，并解释了为什么一些儿童疾病经常一起出现。(C)1998 Elsevier Science B.

The primary aim of this paper is to explore some of the issues surrounding the concept of DCD as a "specific" learning difficulty. Questions relating to the assessment and identification of DCD are addressed. The arguments we present are derived from data obtained in a study which compared 224 children referred because of learning and attention problems (but not motor difficulties) and 155 typically developing children. These 379 children were all assessed on a range of formal and informal tests, including several sensorimotor tests. Working criteria for classifying a child as DCD were derived. In addition to the high prevalence figures obtained for DCD in this group of children, the degree of comorbidity observed between DCD and the other developmental disorders treading disability and attention-deficit/hyperactivity disorder) was also striking. These results prompted us to re-evaluate the usefulness of discrete diagnostic categories, and to consider a reconceptualization of childhood disorders in general. It is proposed that the comorbidity found in childhood disorders reflects a single underlying etiology: Atypical Brain Development. This deficit may be manifested in a variety of ways, including DCD, and explains why some childhood disorders are so often seen together. (C) 1998 Elsevier Science B.V. All rights reserved.
